B = boxes
80 ÷ 20 = b
80 ÷ 20 = 4
To make it easy you can do 8 ÷2 = 4 which makes the same answer :)
She needs 4 boxes
In order the numbers are 20, 29, 32, 37, 42.
So that means the median is 32. In order for the median to stay the same one of the three data values must be 32 as well as adding a number to each side of the ends. One 32 or less another 32or more.
The mean right now is: 20+29+32+37+42=160 and there are 5 values.
Mean: 160/5=32
For it to increase by 10 it has to be 42.
extra 3 numbers I used were 31, 32, & 113 (those are your answer)
Answer:
The answer is below
Step-by-step explanation:
The question is not complete, but I would solve a similar question:
Find the distance between the two points shown on the coordinate plane. (Round your answer to the
nearest tenth.)
Solution:
The coordinate plane is a plane formed by the intersection of the vertical line and the horizontal line. The vertical line is known as the y axis and the horizontal line is the x axis. The y axis and x axis intersect at a point known as the origin.
The distance between two points on the coordinate plane is given by:
Given points (-2, -1) and (2, 3), the distance is:
Since both equal y
x-1=y=2x+1
x-1=2x+1
minus x both sides
-1=x+1
minus 1 both sides
-2=x
value of x is -2
